Suzuki 2.5 HP DF2.5S5 Outboard Motor

Description

If you have never owned an outboard, the Suzuki DF2.5S5 for sale is a good place to start. It is a new 2.5 horsepower four stroke with a 15 inch short shaft, a tiller handle and a rope start. It weighs about 29 lb, carries its own small fuel tank and needs no battery. We stock it new in the carton, show the price on this page and ship it worldwide.

This page is written for first-time buyers and for anyone replacing a lost or worn out small motor. We explain the terms in plain words, what the motor will and will not do, how to set it up and how to keep it running. Before you pay, we send you a delivery quote for your country, so there are no surprises on the freight bill.

Suzuki DF2.5S5 for sale: Specifications

Small details can differ between production runs, so rely on the paperwork in the carton. For the wider small-engine range, see Suzuki’s 2.5 to 30 HP outboard page.

New to Outboards? Start With the Suzuki DF2.5S5 for sale

An outboard is simply an engine, a leg and a propeller that hang off the back of your boat. You steer by swinging the whole motor. On the Suzuki DF2.5S5 for sale the tiller handle does this, and the twist grip on the end is the throttle. Turn it towards you for more speed. There is no gear lever for reverse, so to go backwards you turn the motor around.

That simplicity is why we recommend the Suzuki DF2.5S5 for sale to beginners. There is no key, no battery, no cables and no electronics to learn. Fill the tank, pull the rope and go.

What the Letters in DF2.5S5 Tell You

DF is Suzuki’s four stroke family. 2.5 is the horsepower. S is the 15 inch short shaft. The 5 at the end is the production series, and it separates this motor from the Suzuki DF2.5S2 sold earlier. For the 20 inch version, look at the Suzuki DF2.5L4 or the Suzuki DF2.5L2.

Notice what is not there. No E means no electric start. No T means no power tilt. This is a manual motor from end to end, and that keeps the price and weight down.

Will the Suzuki DF2.5S5 for sale Fit and Move My Boat?

Check three things before you buy. First, the transom height: a short shaft suits a transom of about 15 inches. Second, the maximum power rating on the boat plate. Third, the weight you plan to carry. A 2.5 HP motor works best on a boat that is light and small, with one or two people on board.

If those fit, the Suzuki DF2.5S5 for sale will move the boat at an easy pace and use very little fuel. If you want to plane a loaded boat, you need more power. Look at the Suzuki DF4AS2 or the Suzuki DF4AS5 instead.

The First Day With the Suzuki DF2.5S5 for sale

1. Check the oil level on the dipstick.
2. Fill the built-in tank with fresh unleaded petrol.
3. Clamp the motor to the centre of the transom and tighten the screws evenly.
4. Attach a safety line from the motor to the boat.
5. Put the motor in the water, or on a flushing adaptor with water running.
6. Open the fuel vent, set the choke and pull the rope smoothly.
7. Check that a stream of water leaves the cooling outlet.
8. Clip on the kill switch lanyard and set off gently.

Never start the Suzuki DF2.5S5 for sale without water going through it. Even a few seconds dry can damage the impeller.

How the Suzuki DF2.5S5 for sale Behaves on the Water

It is a quiet motor for its size. The exhaust leaves through the propeller area, so you hear a low hum rather than a sharp buzz. The tiller is steady at low speed and the throttle holds its position with the friction control. At full throttle it works hard, so cruise below that when you can.

We do not quote speeds or fuel burn, because they depend far more on your boat and load than on the motor. A light dinghy will feel lively. A heavier boat will feel steady and slow. Ask yourself how fast you actually need to go, and the answer is usually less than you think.

Break-In Rules for the Suzuki DF2.5S5 for sale

New engines like gentle treatment, and the Suzuki DF2.5S5 for sale is no different. For the first hours, vary the revs, avoid long runs at full throttle and keep the motor clean. Change the oil at the first service in the owner’s manual. This helps the rings seat and keeps oil use low for the life of the motor.

Servicing the Suzuki DF2.5S5 for sale

• Flush with fresh water after salt or muddy water use.
• Change the engine oil at the first service, then each season.
• Change the gear oil each season and look for a milky colour.
• Replace the spark plug when worn.
• Check the valve clearance at the manual’s interval.
• Replace the water pump impeller every two or three seasons.
• Keep fuel fresh and drain the carburettor before long storage.

These are simple jobs, and many first-time owners do them in the driveway. Genuine plugs, oil and impellers are listed on the Suzuki genuine parts and accessories page.

Fuel and Oil for the Suzuki DF2.5S5 for sale

Use fresh unleaded petrol in the tank of the Suzuki DF2.5S5 for sale and engine oil in the sump. Do not mix them. The sump is tiny, about 0.3 litre, so check the level before every trip. Use SAE 10W-30 or 10W-40. Fuel that has sat for months is the main cause of poor starting, so buy small amounts and use them.

Salt Water Care for the Suzuki DF2.5S5 for sale

The Suzuki DF2.5S5 for sale is rated for salt water and has a multi-layer finish. It still needs a rinse. After every salt trip, flush the cooling passages with fresh water, wipe it down and let it dry. A light spray of corrosion inhibitor on exposed metal helps.

Storing the Suzuki DF2.5S5 for sale Between Trips

Close the fuel vent, burn off or drain the fuel in the carburettor, and store the Suzuki DF2.5S5 for sale in the position shown in the manual. Keep it dry and covered. A motor stored the wrong way round can let oil into the cylinder, which causes smoke and hard starts.

Common Problems Beginners Meet

It will not start. Check the fuel is fresh, the vent is open, the lanyard is in and the plug is dry.

It starts and then stops. The carburettor may be dirty, or the choke may be wrong.

It overheats. Check the water stream. A weak stream means a blocked outlet or a worn impeller.

It vibrates. Look for a bent propeller blade or a loose clamp.

It runs but the boat is slow. The boat is overloaded, weed is on the prop, or the prop is damaged.

Outboard Words Explained for the Suzuki DF2.5S5 for sale Buyer

• Transom: the flat board at the back of the boat where the motor clamps on.
• Shaft length: the distance from the clamp to the anti-ventilation plate. Short is 15 inch and long is 20 inch.
• Tiller: the handle you steer with.
• Choke: a lever that gives the cold engine a richer mixture to start.
• Lanyard: the cord that stops the engine if you fall away from the helm.
• Gearcase: the lower housing that holds the propeller shaft and gears.
• Impeller: the small rubber pump that pushes cooling water around the engine.

Knowing these terms makes it easier to follow the manual and to talk to a dealer about your Suzuki DF2.5S5 for sale.

Where to Mount the Suzuki DF2.5S5 for sale

Put the Suzuki DF2.5S5 for sale on the centre line of the transom unless your boat has a motor well or side bracket. Make sure the area is flat and strong, and not cracked or soft. On an inflatable, use a transom board rated for outboards. On a wooden boat, check there is no rot where the clamp bites.

If the boat has an offset transom, or you are using a bracket on a yacht, check that the bracket is rated for the motor weight and that the motor cannot swing into the rudder or hull. A good bracket plus a safety line keeps the Suzuki DF2.5S5 for sale secure through waves and wakes.

Starting the Suzuki DF2.5S5 for sale by Rope

Most beginners yank the rope too hard. Pull the handle until you feel the engine come up against compression, then give a smooth, quick pull through to the end. The Suzuki DF2.5S5 for sale has a compression reduction system, so the effort is lower than you expect. Keep one foot braced and the boat tied to the dock.

If it does not start after six or seven pulls, stop. Check the fuel, the choke, the vent and the plug. Pulling thirty times floods the engine and only wastes your arm.

Reading the Cooling Water Stream

When the engine runs, a thin jet of water leaves a small hole on the side of the motor. This tells you the water pump is working. If the jet is steady and strong, all is well. If it is weak or stops, shut the motor down at once, because a hot engine fails quickly. The usual cause is a blocked outlet, and a thin wire can clear it. If the jet is still weak, the impeller is the next suspect.

Handling Fuel Safely With the Suzuki DF2.5S5 for sale

Fill the tank ashore, not on the boat, so spills do not end up in the bilge. Use fresh unleaded petrol and wipe up any drips. Close the vent when carrying the motor. Do not smoke near fuel, and do not refuel a hot engine. These habits matter more with a motor like the Suzuki DF2.5S5 for sale because the small tank is close to the exhaust.

Carrying and Transporting the Suzuki DF2.5S5 for sale

At about 29 lb the Suzuki DF2.5S5 for sale is easy to lift using the handle. Lay it on the side the manual shows, with the fuel closed, and put an old towel or bag under it. Do not lay it on the wrong side, because oil can run into the cylinder. Never carry the Suzuki DF2.5S5 for sale on a plane with fuel in it. Drain it first and ask the airline about its rules.

Safety Gear for Small Boats

Wear a life jacket when you use the motor, clip on the kill switch lanyard and carry oars or a paddle. Take a whistle, a small anchor, a bailer and a basic tool kit with a spare plug. Check the weather before you leave. A 2.5 HP motor does not have the power to fight a strong wind or tide, so keep close to shore and plan an easy way home.

Insurance, Theft and Records

Small outboards get stolen often. Use a lockable clamp or a cable. Take the Suzuki DF2.5S5 for sale home after use if the boat sits on a beach or an open mooring. Write down the serial number and keep the invoice, because both help with insurance and with warranty.

Hot and Cold Climates

In warm and silty water, watch the cooling stream and replace the impeller more often. In cold weather, use the choke as the manual describes. Before a freeze, drain the fuel and make sure no water stays in the lower unit or cooling passages.

Warranty on the Suzuki DF2.5S5 for sale

The Suzuki DF2.5S5 for sale ships with Suzuki factory warranty paperwork. The term depends on your region and the production series, and leisure use is treated differently from commercial use. Keep your receipt and service records, and ask us about cover in your country before you order.

What Comes in the Carton

• Suzuki DF2.5S5 powerhead, midsection and gearcase with the propeller fitted
• Owner’s manual and warranty paperwork
• Standard Suzuki fittings from the factory

Fuel, oil and any bracket are not included. Ask before you order and we will tell you exactly what ships with your motor.

Before You Order the Suzuki DF2.5S5 for sale

• Measure the transom to confirm that a 15 inch shaft is right.
• Check the maximum rated horsepower and the transom load rating.
• Decide if you can live without electric start and reverse gear.
• Plan where the motor will be stored and how you will carry it.
• Tell us your country so we can quote shipping.

If anything is unclear, ask us. A few minutes of questions now saves trouble when the carton arrives.

What the Suzuki DF2.5S5 for sale Costs to Own

The purchase price is on this page. After that, the running costs are small: fuel, a litre of engine oil a year, a spark plug, gear oil and an impeller every couple of seasons. There is no battery to replace and no electronics to repair. Most owners find that the Suzuki DF2.5S5 for sale costs less to keep than a decent pair of oars and a life jacket.

Upgrading Later From the Suzuki DF2.5S5 for sale

Many people start with a 2.5 and move up later when their boating grows. If you buy a bigger boat, you can keep the Suzuki DF2.5S5 for sale as a spare or sell it on. A clean, serviced motor with its paperwork holds its value well because demand for small Suzukis stays steady. If you want more power next time, the 4 HP and 6 HP models in our shop are the obvious steps.

Looking After the Propeller on the Suzuki DF2.5S5 for sale

The propeller on the Suzuki DF2.5S5 for sale is a fixed three blade aluminium unit. It is cheap to replace and designed to take a knock, but a bent blade is a problem you should not ignore. Look at it after every grounding. If it is chipped or bent, the motor will vibrate, and the vibration can wear the gearcase seal. A new genuine propeller costs far less than a gearcase repair.

Also check for fishing line. Line wraps tightly around the propeller shaft behind the prop and can cut through the seal. Tilt the motor up now and then and look.

Why Beginners Like the Suzuki DF2.5S5 for sale

People new to boating tell us the same things. The Suzuki DF2.5S5 for sale is light enough to carry without help, quiet enough that it does not spoil the day, and simple enough that they trust themselves to service it. It does not ask for a battery charger, a key or a wiring harness. The rope is the only moving part you operate.

The other thing they mention is confidence. Because the Suzuki DF2.5S5 for sale is a Suzuki, spares and advice are easy to find nearly everywhere in the world. A plug, a gasket or an impeller can be sourced in most ports, and that matters to anyone who plans to travel with their boat.

Is the Suzuki DF2.5S5 for sale Better Than a Used Motor?

A used outboard can be cheap, but you inherit the history. You do not know how it was stored, whether it was flushed, whether the impeller has been replaced or whether the oil was ever changed. A new Suzuki DF2.5S5 for sale arrives with fresh seals, a fresh warranty and no hidden damage. For a motor this price, we think new is the safer way to buy, particularly when it is shipped to a place where repair shops are far away.

Our Honest View on the Suzuki DF2.5S5 for sale

We like this motor because it does a small job well. It will not win races and it does not try to. If your boat is small and your trips are short, the Suzuki DF2.5S5 for sale gives you a dependable engine that starts easily and costs little to look after. If your needs are bigger, we will tell you, and point you to a different Suzuki.
